BACKGROUND: Volume overload is frequent in diabetics undergoing peritoneal dialysis (PD), and may play a significant role in the excess mortality observed in these patients. The characteristics of peritoneal water transport in this population have not been studied sufficiently. METHOD: Following a prospective, single-center design we made cross-sectional and longitudinal comparisons of peritoneal water transport in 2 relatively large samples of diabetic and nondiabetic PD patients...

Acetaminophen (paracetamol) (PAR) is one of the most popular non-steroidal anti-inflammatory drugs (NSAIDs) with analgesic and antipyretic properties consumed worldwide and often detected in the aquatic environment. Due to the fact that PAR induces oxidative stress in mammals, the aim of this study was to evaluate if similar effects were observed in oysters Crassostrea gigas, given their economic and ecological importance and worldwide distribution. Oysters were exposed for 1, 4 and 7 days to two different sublethal PAR concentrations (0, 1 and 100μgL(-1))...

The energy required to drive lens transparency is derived from the metabolism of glucose. In the lens, the uptake of glucose is likely to involve either facilitative glucose uptake mediated by members of the GLUT family or Na(+) dependent glucose uptake via members of the SGLT family, or both. While GLUT1 and GLUT3 have previously been identified in the rat lens, the expression of SGLTs is unknown. Since antibodies directed against the N and C-terminal epitopes of the GLUT and SGLT family are now commercially available, the purpose of this study is to extend our screening of glucose transporters in the rat lens to include the SGLTs and compare the expression profiles of GLUTs and SGLTs in the different regions of the lens...

Oxidized tyrosine products are commonly found in food with high protein content and have been demonstrated to cause damage of liver and kidney in our previous studies. Dityrosine (Dityr) is a typical oxidized tyrosine product. Due to its structural homology with thyroid hormones T3, we assumed that one of the endocrine systems most likely considered in connection with its disruption by Dityr may be the T3 action. T3 plays important roles in insulin synthesis, and thyroid hormone resistance (RTH) is associated with the impairment of glucose metabolism...

Alzheimer's disease (AD) is progressive neurodegenerative disorder characterized by accumulation of senile plaques, neurofibrillary tangles (NFT) and neurodegeneration. The diabetes mellitus (DM) is one of the risk factors for AD pathogenesis by impairment in insulin signaling and glucose metabolism in central as well as peripheral system. Insulin resistance, impaired glucose and lipid metabolism lead to the Aβ (Aβ) aggregation, Tau phosphorylation, mitochondrial dysfunction, oxidative stress, protein misfolding, memory impairment and also mark over Aβ transport through central to peripheral and vice versa...

BACKGROUND: Although male gender, aging, hypertension, dyslipidemia, and smoking are common risk factors for abdominal aortic aneurysm, diabetes mellitus is an independent negative risk factor. In aneurysm tissue, matrix metalloproteinases (MMPs) expressed by activated macrophages degrades extracellular matrix proteins. In our previous experimental study, we demonstrated that the aneurysmal formation and macrophage activity were suppressed by inhibiting mimicking hyperglycemia (HG) through upregulation of glucose-sensing nuclear receptor, Nr1h2...

INTRODUCTION: Transplacental fetal glucose supply is predominantly regulated by glucose transporter-1 (GLUT1). Altered expression and/or function of GLUT1 may affect the intrauterine environment, which could compromise fetal development and may contribute to fetal programming. To date it is unknown whether placental GLUT1 is affected by preeclampsia, which is often associated with intrauterine growth restriction (IUGR). We addressed the hypothesis that preeclampsia leads to decreased expression and function of placental GLUT1...

Type 2 diabetes mellitus (T2DM) is a common and increasingly prevalent metabolic disorder, and effective preventive strategies against this disease are needed. The aim of the present study was to evaluate the potential antidiabetic properties of a dietary apple/kale extract (AKE), which was rich in phlorizin and flavonoids, in laboratory mice. Mice were fed a control diet, a Western-type high-sugar, high-fat diet (WTD), or a WTD plus AKE for 10 weeks. Body weight, food and energy intake, body composition, and blood glucose level were recorded in addition to the postprandial rise in blood glucose concentration after a single administration of glucose (oral glucose tolerance test, OGTT)...

The leptin gene was transferred into the liver of streptozocin- and high fat diet-induced type 2 diabetic (T2D) mice by hydrodynamic-based gene delivery. The food intake, water consumption, glucose concentration, and triglyceride, total cholesterol levels of T2D mice were significantly decreased. Meanwhile, plasma leptin was remarkably increased after gene transfer for 2, 3, 5, and 7 days, while plasma adiponectin was also significantly increased at day 2. To understand the mechanism of action of leptin on T2D mice, gene expressions related to glycometabolism and energy metabolism in the liver, epididymal adipose tissue, hypothalamus, and muscle were measured...

Potassium (K) deficiency is a common abiotic stress that can inhibit the growth of fruit and thus reduce crop yields. Little research has been conducted on pear transcriptional changes under low and high K conditions. Here, we performed an experiment with 7-year-old pot-grown "Huangguan" pear trees treated with low, Control or high K levels (0, 0.4, or 0.8 g·K2O/kg soil, respectively) during fruit enlargement and mature stages. We identified 36,444 transcripts from leaves and fruit using transcriptome sequencing technology...

The solute carrier family 25 (SLC25) drives the import of a large diversity of metabolites into mitochondria, a key cellular structure involved in many metabolic functions. Mutations of the mitochondrial glutamate carrier SLC25A22 (also named GC1) have been identified in early epileptic encephalopathy (EEE) and migrating partial seizures in infancy (MPSI) but the pathophysiological mechanism of GC1 deficiency is still unknown, hampered by the absence of an in vivo model. This carrier is mainly expressed in astrocytes and is the principal gate for glutamate entry into mitochondria...

GLUT1 facilitates the down-gradient translocation of D-glucose across cell membrane in mammals. XylE, an Escherichia coli homolog of GLUT1, utilizes proton gradient as an energy source to drive uphill D-xylose transport. Previous studies of XylE and GLUT1 suggest that the variation between an acidic residue (Asp27 in XylE) and a neutral one (Asn29 in GLUT1) is a key element for their mechanistic divergence. In this work, we combined computational and biochemical approaches to investigate the mechanism of proton coupling by XylE and the functional divergence between GLUT1 and XylE...
